Used in research to study the role of the 5-HT6 receptor in neurological conditions such as Alzheimer's disease and schizophrenia. It acts as a selective antagonist, helping scientists understand serotonin signaling pathways and evaluate potential cognitive-enhancing drugs. Due to its specificity, it is valuable in preclinical studies assessing the effects of 5-HT6 receptor modulation on memory, learning, and behavior. Not intended for clinical use in humans.
